What is the difference between the meaning and usage of for ever and forever in British English? From what I could gather from my online research,

forever means :

  1. (also for ever) for all future time; for always
  2. continually


for ever - Oxford has only Eng-Ger, Eng-It and Eng-Sp entries for it(apart from being redirected to forever's definition), Collins says it is an adverb meaning forever.

  • Forever meaning “constantly” is only one sense of the word in American English, and far from the most common. We use it more to mean “eternity” or “a long time.” See en.wiktionary.org/wiki/forever#Usage_notes for a discussion of British vs American usage. – Bradd Szonye May 20 '13 at 6:01
  • Those do not look like quotes from a dictionary. Those look like (poorly punctuated) quotes from random dudes off the Internet. I wonder why nobody ever uses a dictionary anymore. Dictionaries were precisely invented for the whole purpose of looking up the meanings of words; random dudes were not. – RegDwigнt May 20 '13 at 11:12

    Good question. Perhaps GR on ELU, but can be asked on ELL ell.stackexchange.com -- Forever is not for ever in all contexts in BrE. They mean different things. For one, the phrase has the preposition for as in any similar phrase for the needed prepositional sense. The word forever is used as an adverb or adjective/ noun. Suggested migration to ELL. – Kris May 21 '13 at 6:45

  • @Kris The dictionary says for ever is an adverb too. – tanvi May 21 '13 at 11:19
